Hydro Bloom 1 Part is a flowering and fruiting stage specific nutrient. It’s suitable for NFT (Nutrient Film Technique), expanded clay, perlite and various other inert soilless substrates. The HYDRO BLOOM formula incorporates higher levels of phosphorous, potassium and trace elements to support the transition from growth to flowering and eventual final harvest. The formulation compliments the HYDRO GROWTH formula. The nutrient levels are carefully formulated to ensure that the perfect ratios between nitrogen and phosphorous are achieved to ensure the plant gains maximum flowering and fruiting benefit. Calcium, potassium, magnesium, sulphur and trace elements are also optimised to maximise availability.
